发明名称 RETROREFLECTIVE MARKER-TRACKING SYSTEMS
摘要 A marker-tracking system includes an object, a marker illuminating device, a marker sensing device, and a computing device. The object includes a first retroreflective marker having a shape that is substantially defined by two spherical caps of different radii that are disposed substantially concentric in relation to one another. The marker illuminating device substantially illuminates the first retroreflective marker, the marker sensing device detects the illuminated first retroreflective marker and generates first data indicative of the location of the illuminated first retroreflective marker in space, and the computing device processes the first data generated by the marker sensing device to determine a position and/or orientation of the object in space.
